"Could the holy grail of turning salt water to drinkable water finally be upon us? A new report from Interesting Engineering seems to suggest that could be the case - detailing a new nanofiber membrane, developed by Yunchul Woo and his team at the Korea Institute of Civil Engineering and Building Technology, that appears to be "stable in the long term" for desalinization. And it can be done "in minutes", the report says. Membranes had been used in the past, but there is often a challenge in keeping them dry for long periods of time. When they become wet, their filtration characteristics become ineffective and large amounts of salt can pass through. Woo's team has created a membrane "made of nanofibres that have been fabricated into a three-dimensional hierarchical structure" by using a technology called "electrospinning". This new membrane is said to be highly water repellant. "
